Decolorization of dyeing wastewater and characterization of flocs during coagulation by a new composite coagulant.

Abstract

A composite coagulant, polymeric aluminum ferric chloride-poly-epichlorohydrin-ethylenediamine (PAFC-EPI-ETA), was synthesized and then used for the treatment of synthetic reactive brilliant red (RBR) dyeing wastewater. Effects of (Fe+Al) to EPI-ETA mass ratio (P) on the color removal and zeta potential were investigated under different coagulant dosages… (More)
